Awesomely powerful and incredibly intelligent, Dark Scorponok was once widely feared by Decepticons and Autobots alike, until his chassis was destroyed by Megatron. His mind and memory shattered, only partially operational and powered by the might of Unicorn - some of which he managed to absorb - he hungers for a return to full functionality. Even in his partly destroyed state, his mech-venom sting and super-strong claws are a threat to all but the most powerful beings, and his return heralds a new era of fear for all who stand in his way.
This steadfast Autobot is often annoyed by his hyperactive partner Scattorshot, but he nontheless takes his duties very seriously, and will follow thorugh on his orders no matter what. Jetfire has been assigned by Optimus Prime the difficult task of protecting Earth while keeping the Autobot presence a secret and searching for the Earth Planet Key. Jetfire would much rather be fighting in the front lines alongside his leader, but his strategic genius and status as the upstanding, honorable second-in-command of the Autobots make him an invaluable asset at the Autobot base.
Scourge is the brutal and awesomely powerful ruler of the Jungle Planet. He views any display of kindness, compassion or generosity as weakness, and he hates weakness. Cold, distant, and prone to violent rage against those he views as lesser creatures, he holds most of the Jungle Planet firmly in his transmetal claw. Those defying him are likely to experience the searing heat of his stellar plasma breath, or the bite of his axe as their final sensation before their spark is extinguished. Overhaul, Snarl, and the Jungle Planet rebels will find him to be the most powerful foe they have ever faced.
